UNITED STATES F. WALTER BOYER, OF WADSWORIH, OHIO.

NoNcLoGGrNG SPRAY NozzLE.

Application filed September 22, 1923. Serial No. 664,304.

To all whom i may concern:

Be it known that'Dr. F. WAL'riLnBOYER, citizen of the United States,residing at Wadsworth, in the county of Medina and State of Ohio, hasinvented certain new' and a twopiece non-clogging spray nozzle which.

will preferably be used for handling rewerage and disposing of the sameby spraying in the process of aeration, but which also may be usedefficiently in connection With cooling hot water from condensers,breaking up deep well water into tine spray to liberate the irontherefrom by bringing the same into contact with the oxygen of the air,and many other purposes.

Another object of the invention is to pros vide a non-clogging spraynozzle for use in handling sewerage and disposing of the same hyspraying in the process of aeration, and providing a removable knife orbaille having a serrated edge within said nozzle for break- .ing up anyparticles in the liquid so that the same will readily be dischargedthrough the orifice in the nozzle.

A still' further object of the invention is to provide a suitable twopiecel nozzle for use in disposing of sewerage by the aeration process,which will be highly eflicient in operation and quite inexpensive tomanufacture.

Other objects will appear as the description proceeds.

ln the accompanyingr drawings which form a part of my application,

Vig. 1 is a plan view of my improved nozzle with the top or cap memberremoved therefrom. v Fig. 2 is a sectional vienr taken on the line 2---2of Vig. 1, and showing the top or cap member in section and in itsoperative posi' tion Like characters of reference are used throughoutthe following specification and the accompanying drawings to -designatecorresponding parts.

The main body portion 1 of the nozzle. is

substantially cup 'shaped and isA l'provided with spaced laterallyextending bifurcated ears and an integrally formed water inlet tube orpipe 3 which is attached to the body portion at a tangent. The outer endofthe tube or pipe 3 is provided with a coupling 4 to be attached to thesupply line through which the sewerage will be discharged.

A curved inwardly proJecting knife or` baflie 5 is attached to the innerwall. of the y main body portion 1 and is securely held in position bymeans of the screws (3. The forward-edge of the knife 5 is serrated asat'7 solas to provide a, plurality of teeth for more eflicientlybreaking up the sewerage.

A detachable dome shaped cap member 8 is provided at its lower edge withan annular seat 9 which is adapted to engage and seat' upon a washer 10on the upper annular surface of the body portion 1. The cap member 8 isalso provided at its inner rtion with a downwardly extending annu ar 11which is adapted to seat down on the inside of the annular wall of thebody 1 so as to properly position the cap member with respect thereto.The cap member 8 is provided with a, plurality of integrally formedradially extending spaced bi furcated ears 12, which are adapted to bealigned with the bifurcated ears 2 and to beheld in that position bymeans of the bolts 13 whch'extend in-to and between the bifurcations.andv the locking nuts 14.

A restricted orifice 15 is formed mijnen' the upper end of the capmember 8. The wall of the cap member is flaredv outwardly as at 16 fromthe orifice L'vtothe outer edge of said cap member to allow the spray tospread out as it passes through the nozzle.

F rom the foregoing description .it will be.

apparent that when the nozzle is attached to the discharge pipe line,the sewerage will enter the nozzle at'a tangent and sweep around thecurved inner wall until it impinges against. the serrated edge 7 of theknife or baille which will break up any particles of the sewerage sothat the same will readily pass up and through the orifice due to thecentrifugal whirl of the said sewerage.

The dome shaped formation of the inside of the wall of the cap member 8and the flared wall on the outside of the orifice 15 provides for chewide 5pm mg of the sewerage to be aerated in a hig ner.

Many minor changes 4in detail of construction-may be resorted to Withoutdeparture from the spirit of the invention.

ly efficient man- Having thusrdescribe'fl my invention .what

I claim as nev;1 and desire to secne byLetters Patentl of the United'Sta-tes is:

1. A spray nozzle' for 'disintegrating 'sewerage -and the likeveomprisi'n'g' a cylindrical body part having -a tangential inletconn'ection, aA `serrated blade inwardly directed from its inner Wall,and a pluralityvof outwardly directed lugs arranged 'in pairs, andadome-` shaped cover `memberhaving a rest-rlcted discharge .orifice and aplurality 'of'ont-"i 'having a restricted discharge oriiice andan inletorifice transversely thereto, and a baffle within said chamberagainstrwhich' the incoming fluidwill imp-inge, said baffle comprising avertically disposed serrated blade arranged' radially at one side oftheinlet orifice. r A v In testimony whereof I afiix my signature.
